How gravity is created? Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an […]
Which shows the weight of an atom?
Which shows the weight of an atom? The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 […]
Does the Eclipse affect sleep?
Does the Eclipse affect sleep? You should not sleep during the duration of the eclipse. So you can’t eat, you can’t have sex — and you’re not allowed to sleep either. Three pretty major activities have been cut out of the equation if you’re superstitious. Is it safe to go outside during solar eclipse? Dos […]
Which scale is use for absolute zero?

How do you classify archaea?
How do you classify archaea? Archaea, (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, including plants and … What two groups does […]
What is the effective resistance between A and D?
What is the effective resistance between A and D? D=5Ω+10Ω+5Ω=20Ω What is the effective resistance in the given circuit? The effective resistance of a circuit containing resistances in parallel is smaller than any of the individual resistances. For example : R1=2Ω and R2=3Ω ∴ Effective resistance Rp1=R11+R21. Maximum effective resistance will be when all the […]
Why is the sodium potassium pump so important to the human body?
Why is the sodium potassium pump so important to the human body? In the kidneys the Na-K pump helps to maintain sodium and potassium balance in our body. It also plays a key role in maintaining blood pressure and controls cardiac contractions. What human body system depends on the sodium potassium pump? nervous system Why […]
What caused the 5 mass extinctions?
What caused the 5 mass extinctions? The most commonly suggested causes of mass extinctions are listed below. Flood basalt events. The formation of large igneous provinces by flood basalt events could have: Sea-level falls. Impact events. Global cooling. Global warming. Clathrate gun hypothesis. Anoxic events. Hydrogen sulfide emissions from the seas. Can global warming cause […]
How is projectile motion used in real life?
How is projectile motion used in real life? In real life, the projectile motion finds applications in sports. Playing basketball, football is examples of projectile motion in real life. While throwing a basketball into the basket, the player shoots the ball in such a way that the flight taken by the ball is in the […]
